(Test Method)Standard Test Method for Adhesion and Cohesion of One-Part Elastomeric Solvent Release Sealants
Standard Test Method for Adhesion and Cohesion of One-Part Elastomeric Solvent Release Sealants
SCOPE
1.1 This test method is a laboratory procedure that determines the adhesion and cohesion performance of one-part elastomeric, solvent release sealants at high and low temperatures by the extension and compression of test specimens.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific precautionary statement, see Note 2.
